| inlinestaticinherited

Return the total number of voxels represented by this LeafNode.

## ◆ skipCompressedValues()

void skipCompressedValues | ( | bool | seekable,
|  | std::istream & | is,
|  | bool | fromHalf
| ) |  |
| inlineprotectedinherited

## ◆ stealNode()

NodeT * stealNode | ( | const Coord & | ,
|  | const ValueType & | ,
|  | bool |
| ) |  |
| inlineinherited

## ◆ stealNodes()

void stealNodes | ( | ArrayT & | ,
|  | const ValueType & | ,
|  | bool |
| ) |  |
| inlineinherited

## ◆ str()

std::string str
| inlineinherited

Return a string representation of this node.

## ◆ streamingSize()

size_t streamingSize | ( | bool | toHalf = `false` | ) | const
| inherited

## ◆ swap()

void swap | ( | Buffer & | other | ) |
| inlineinherited

Exchange this node's data buffer with the given data buffer without changing the active states of the values.

## ◆ topologyDifference()

void topologyDifference | ( | const LeafNode< OtherType, Log2Dim > & | other,
|  | const ValueType & |
| ) |  |
| inlineinherited

Difference this node's set of active values with the active values of the other node, whose `ValueType` may be different. So a resulting voxel will be active only if the original voxel is active in this LeafNode and inactive in the other LeafNode.

The last dummy argument is required to match the signature for InternalNode::topologyDifference.

Note
  This operation modifies only active states, not values. Also, because it can deactivate all of this node's voxels, consider subsequently calling prune.

## ◆ topologyIntersection()

void topologyIntersection | ( | const LeafNode< OtherType, Log2Dim > & | other,
|  | const ValueType & |
| ) |  |
| inlineinherited

Intersect this node's set of active values with the active values of the other node, whose `ValueType` may be different. So a resulting voxel will be active only if both of the original voxels were active.

The last dummy argument is required to match the signature for InternalNode::topologyIntersection.

Note
  This operation modifies only active states, not values. Also note that this operation can result in all voxels being inactive so consider subsequently calling prune.

## ◆ topologyUnion()

void topologyUnion | ( | const LeafNode< OtherType, Log2Dim > & | other,
|  | const bool | preserveTiles = `false`
| ) |  |
| inlineinherited

Union this node's set of active values with the active values of the other node, whose `ValueType` may be different. So a resulting voxel will be active if either of the original voxels were active.

Note
  This operation modifies only active states, not values.

## ◆ touchLeaf()

PointIndexLeafNode * touchLeaf | ( | const Coord & |  | ) |
| inline

Return a pointer to this node.

## ◆ touchLeafAndCache()

PointIndexLeafNode * touchLeafAndCache | ( | const Coord & | ,
|  | AccessorT & |
| ) |  |
| inline

## ◆ transientData()

Index32 transientData | ( |  | ) | const
| inlineinherited

Return the transient data value.

## ◆ valueMask()

const NodeMaskType & valueMask | ( |  | ) | const
| inlineinherited

## ◆ voxelizeActiveTiles()

void voxelizeActiveTiles | ( | bool | = `true` | ) |
| inlineinherited

No-op.

This function exists only to enable template instantiation.

## ◆ writeBuffers()

void writeBuffers | ( | std::ostream & | os,
|  | bool | toHalf = `false`
| ) |  | const
| inline

## ◆ writeTopology()

void writeTopology | ( | std::ostream & | os,
|  | bool | toHalf = `false`
| ) |  | const
| inlineinherited

Write out just the topology.

Parameters

  os | the stream to which to write
  toHalf | if true, output floating-point values as 16-bit half floats
